>regret is worse than rejection
Usually they apply this one to justify their pathetic pick up artist behavior.
In reality, any self respecting man will hate any rejection from a woman. Men do not like to put themselves at the complete mercy of others and then have themselves denied. It hurts your dignity. It teaches you that women have the power and need to be appeased and begged, and that you are basically worthless.
Regret? I don't regret not hitting on women like a horny dog. My regrets come from not taking opportunities for self improvement and have nothing to do with saying "ayy bby u wan sum fuk" to random girls on the street.
